update_used_tables() should be called after handling derived tables in any case.

Don't writing entries to slave log about binlog_checksum not existing on master if log_warnings is <=1.

This solves the issue of getting a lot of unnecessary errors logged on the slave when connecting to MySQL or an old MariaDB version.


sql/slave.cc:
  Don't write that binlog_checksum doesn't exists on the master if log_warnings <= 1

This only happend when using an ORDER BY on a primary key part, where all other key parts where constant.
Remove of duplicated expressions in ORDER BY (as the old code did this in some strange cases)

- Add --sorted_result to the query

Materialization forced in case if rand() used in view or derived table to avoud several calls of rand for gting value of a field.

Fixed set variable uncachable flag from - it shouldbe a side effect not a random value.

Fix EXPLAIN and CREATE SELECT to join_free() (and, thus, ha_index_end())
before ha_commit_trans().

Fixed a wrong assertion.

This test needs at least 320M for tokudb-max-lock-memory.
Normally tokudb-max-lock-memory is auto-sized to be 1/16th
of the available RAM size, and many our test VMs have 4G of RAM.

The fix for bug #27937 was incomplete: it did not handle correctly the queries
containing UNION with global ORDER BY in subselects.

(better to have an address in the output than ??:0)

don't reset interrupted_query after sending the KILL signal, otherwise
the client won't know it has to stop fetching and printing the data.

a memory leak in save_index() first seen in the test case for mdev-5382.

When marking used columns the function find_field_in_table_ref() erroneously
called the walk method for the real item behind a view/derived table field
with the second parameter set to TRUE.
This erroneous code was introduced in 2006. 

Correct processing of view/derived with no tables added.

"Conditional jump or move depends on uninitialised"
in Item_time_typecast::get_date.

Adding "null_value" into the debug assert condition.

Fix ha_myisammrg::update_create_info() to do what ha_myisammrg::append_create_info() does -
take sub-table names from TABLE_LIST, not reverse engineer tablefile names.

Backport praveenkumar.hulakund@oracle.com-20120127081643-u7dxy23i8yyqarm7 from mysql-5.6

run tokudb suites by default.

tokudb.change_column_all_1000_10 test as --big

- For INSERT ... SELECT ... ON DUPLICATE KEY UPDATE, table elimination should 
  check which tables are referenced in the ON DUPLICATE KEY UPDATE clause.

remove_eq_conds() in the function make_join_statistics().

The earlier pushed fix for the bug was incomplete. It did not remove
the main cause of the problem: the function remove_eq_conds()
removed always true multiple equalities from any conjunct, but did not
adjust the list of them stored in Item_cond_and::cond_equal.current_level.

Simplified the test case for the bug and moved it to another test file.

The fix triggered changes in EXPLAIN EXTENDED for some queries. 

Fixed.
